Only now I have time to put writing in order. It’s the only good part of the quarantine time we live…
This time I bring to you my point of view of the Angstrom CTF I’ve entered in march, from 14th to 19th. I tooked a bit more than the usual ctf’s but it worth it, mostly because I could learn a lot during the game. I think it was the first time I could reverse some stuff (3 challenges) using Ghidra and gdb - it was really cool! 😎
This ctf competition had Misc, Web, Crypto, Binary and Rev categories with 47 total challenges. During the five competition days I could manage to solve ten of them, and the eleventh I took the flag a few minutes after the end of the competition. Bad luck…
I ended up in 592nd place with 575 points. You can view my complete writeup in my github repo.
The organizers release a public repository with the solves for the challenges at https://hackmd.io/@ZX59lFiyRu6ODiM2rFw7Wg/ry5FDNeI8#
